Action

When selecting a day of a month from date picker, with the following settings (with utc parameter) :

<VueDatePicker :model-value="parseModelValue" auto-apply :enable-time-picker="false" :timezone="utc" :month-picker="false" :week-picker="false" :year-picker="false" :year-range="yearRange" utc :min-date="minDateForDatePicker" :max-date="maxDateForDatePicker" :disabled="disabled" :locale="locale" :format="locale === 'fr' && (!isDay && !isMonth && !isWeek) ? 'dd/MM/yyyy' : ''" :input-class-name="disabled ? 'hover:cursor-not-allowed' : ''" @update:model-value="handleDate" />

Result

For exemple when selected from the calendar of VueDatePicker the 6th of November 2024,

The the value passed to handleDate is

With timezone	current result	expected result	correct date translated in UTC
Europe/Paris	2024-11-06 22:59:59.999999	2024-11-06 22:59:59.999999	✅
UTC	2024-11-05 23:59:59.999999	2024-11-06 23:59:59.999999	💥

We use version 10.0 of the library.

I think I ran into the same problem in v9 of the library. Adding the UTC flag shifted the whole day one day backwards. Ended up just working with the returned JS Date object and converting that to a Luxon DateTime first, then outputting in the formats we needed.
